These patients will not be evaluable for hematologic toxicity. At least 5 of every cohort of 6 patients must be evaluable for hematologic toxicity for the dose-escalation part of the study. If dose-limiting hematologic toxicity is observed, all subsequent patients enrolled must be evaluable for hematologic toxicity * A creatinine based on age/gender as follows: * 1 to \< 2 years: Maximum serum creatinine (mg/dL) 0.6 (male), 0.6 (female) * 2 to \< 6 years: Maximum serum creatinine (mg/dL) 0.8 (male), 0.8 (female) * 6 to \< 10 years: Maximum serum creatinine (mg/dL) 1 (male), 1 (female) * 10 to \< 13 years: Maximum serum creatinine (mg/dL) 1.2 (male), 1.2 (female) * 13 to \< 16 years: Maximum serum creatinine (mg/dL) 1.5 (male), 1.4 (female) * 16 to ≤ 39 years: Maximum serum creatinine (mg/dL) 1.7 (male), 1.4 (female) * OR a 24 hour urine creatinine clearance ≥ 70 mL/min/1.73 m\^2 * OR a glomerular filtration rate (GFR) ≥ 70 mL/min/1.73 m\^2.

Patient with any grade of tendon reflex decrease are eligible Exclusion Criteria: * Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as seen in animal/human studies, OR because there is yet no available information regarding human fetal or teratogenic toxicities.
